Members without the ColumnAttribute attribute are also assumed to be persistent. However, they will be mapped to a column with the same column name. A typical example is when auto-properties are used. In this case specifying StorateAttribute or any other attribute can be avoided. Telerik Data Access will still resolve the member properly.
